Components and Materials

The selection of component values for common mode filters need not be a difficult and confusing process. The use of standard filter alignments can be utilized to achieve a relatively simple and straightforward design process, though such alignments may readily be modified to utilize pre-defined component values.

In this column, the author offers a brief summary of a more systematic approach for using ferrite cores on cables. This summary can serve as a “ferrite core checklist” for design and test engineers.

While the selection of components in electrical equipment plays a crucial role, a sound understanding of the characteristics of safety-critical and high-integrity components can provide valuable information about the ways to advance and achieve safety goals.

This article presents a simple method of estimating the parasitics of the three passive circuit components (R, L, C).

Don’t overlook the fact that EMI filters can be used to prevent unwanted RF noise (such as electrical fast transient burst, conducted RF, and some surges) from entering susceptible devices.

Modern lithium batteries require a comprehensive approach to risk assessment and mitigation during product development, and a swift and systematic response when safety concerns arise in the field.

End-product manufacturers can help protect against supply chain disruptions that impact the availability of listed or recognized components by proactively identifying suppliers who can provide substitute components that conform with their listing requirements.

Engineers from the Technical University Munich have created a new supercapacitor which is highly efficient and sustainable.

This article provides an overview of current standards applicable to rechargeable lithium and lithium-ion batteries.
